Kinetics

________: study the rate at which a chemical process occurs.

Concentration is most often expressed in

Molarity.

Stoichiometric factors

________ derived from a balanced equation may be used to relate reaction rates.

Catalysts

________ are not consumed during the course of the reaction.

positive integers

Reaction orders are usually ________ (0, 1, 2…) but can also be fractions or negative numbers.

Elementary step

________: a single event in the course of a reaction.

K

________ is independent of reactant concentration.

Reaction mechanism

________: how the reaction occurs.

rate constant

The ________, k is specific for a particular reaction at a particular temperature.

higher temperatures

At ________, reactant molecules have more kinetic energy, move faster, and collide more often and with greater energy.

Instantaneous reaction rate

________: the rate at which a reaction is proceeding at a specific time and /or conc.

Catalysts

________ speed up reactions by changing the mechanism of the reaction.

Kinetics

study the rate at which a chemical process occurs

Reaction mechanism

how the reaction occurs

Rate of a reaction

the change in the amount of a reactant or product per unit time

Rate expression

mathematical representation of rate of reaction

Average reaction rate

the rate at which a reaction  proceeds over a time period

Instantaneous reaction rate

the rate at which a reaction is proceeding at a specific time and/or conc

Initial reaction rate

the instantaneous reaction rate at "time zero"

Elementary step

a single event in the course of a reaction

Rate order

the sum of the exponents in the rate law

Initial rate

the rate at time zero
